IPC: B60B33/08
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To prevent such fixtures as furniture from falling or moving when an earthquake occurs. SOLUTION: This seismic isolator has a support tray 1 whose upper surface is spherically dented mounted on the floor. Casters 2 consisting of balls 8 which can roll in all directions are attached at legs 13 or on the base of furniture such as a piano and supported on the support tray 1.

And since the upper surface of the support tray 1 is dented, restoring force will be given. In this case, it is preferable that the spherical surface of the support tray 1 be made of a plural number of spherical surfaces of different R's.  In addition, a flexible member or attenuator may be attached between the support tray 1 and the casters 2 to further apply restoring force and attenuating force.

Then, it is judged whether the stroboscope mode is a mode returning to an automatic mode after one-frame photographing or not (S14). When it is judged that photographing is attained by one frame, in a state where a night view or distant view mode is set, the specific command (the resetting of the stroboscope mode) is transmitted (S15). Then, it is judged whether a self mode is set or not (S16) and when photographing is attained in the state where the self mode is set, the specific command (the resetting of the self mode) is transmitted (S17), to feed the film by one frame (S18).
